Failure Time Analysis
The primary objective is to evaluate the durability of the investigational device over its intended use lifetime (i.e. warranty period), specifically relating to any defect in the TPE material. Additionally, to gather information on the rate of side-effects, i.e. skin rashes, sores, etc. Secondary objectives relate to gather information on how amputees use the liner, specifically: * Intensity of use (days/week and hours/day) * Alternation; i.e. switching every other day between liners * Use of personal hygiene or cosmetic products The following performance and safety aspects are to be verified: • The ICEFORM line of devices are durable over their intended use lifetime. Iceform liner and sleeve: Subjects will be asked to use the investigational device as their primary prosthesis for up to 6 months. TPE material durability evaluated through monthly online questionnaires.
